One-lung ventilation (OLV) is an essential technique in thoracic surgery, and double-lumen endobronchial tubes (DLTs) are commonly used. While right-sided DLTs are useful in specific situations, few studies have investigated the prevalence of their use. This study aimed to investigate the current practice of OLV and right-sided DLT usage among anesthesiologists in Japan.
A nationwide cross-sectional survey was conducted in September 2024, targeting 1444 hospitals certified by the Japanese Society of Anesthesiologists. Questionnaires were mailed to anesthesiology departments, inquiring about OLV practices, right-sided DLT usage, challenges, and desired improvements. Responses were collected via postal mail or web, and data were analyzed using descriptive statistics and Chi-square tests.
A total of 768 institutions responded (response rate: 53.2%). Among 761 valid responses, 74.9% performed OLV, and DLTs were the most frequently used device (94.7%). Approximately half (45.8%) of the institutions performing OLV reported never using right-sided DLTs. Frequently recognized challenges included insertion difficulty, positioning difficulty, and unfamiliarity, and 42.1% of institutions expressed a willingness to increase the use of right-sided DLTs if these challenges were resolved. Institutions with a higher annual volume of OLV cases tended to use right-sided DLTs more frequently, but the proportion of institutions unfamiliar with right-sided DLTs was not associated with the number of OLV cases performed.
OLV is widely practiced in Japan, primarily using DLTs, while the use of right-sided DLTs is limited. Concerns over technical difficulties and complications may hinder the use of right-sided DLTs.
单肺通气（OLV）是胸外科手术中的一项重要技术，双腔支气管导管（DLT）是常用的。虽然右侧DLT在特定情况下有用，但很少有研究调查其使用的普遍性。本研究旨在调查日本麻醉医生中OLV的当前实践情况以及右侧DLT的使用情况。
2024年9月进行了一项全国性横断面调查，目标是日本麻醉医师协会认证的1444家医院。向麻醉科邮寄问卷，询问OLV实践、右侧DLT的使用情况、挑战以及期望的改进。通过邮政邮件或网络收集回复，并使用描述性统计和卡方检验分析数据。
共有768家机构回复（回复率：53.2%）。在761份有效回复中，74.9%进行了OLV，DLT是最常用的设备（94.7%）。进行OLV的机构中约一半（45.8%）报告从未使用过右侧DLT。常见的挑战包括插入困难、定位困难和不熟悉，42.1%的机构表示如果这些挑战得到解决，愿意增加右侧DLT的使用。每年OLV病例数量较多的机构倾向于更频繁地使用右侧DLT，但不熟悉右侧DLT的机构比例与进行的OLV病例数量无关。
OLV在日本广泛应用，主要使用DLT，而右侧DLT的使用有限。对技术困难和并发症的担忧可能会阻碍右侧DLT的使用。
